Pages

While trying to print envelopes from Pages, the Printer Options box shows my envelope on a lager piece of paper. It used to show it as an envelope size. When I send it to my printer, I get an error saying it is the wrong paper size for the chosen project, even though I have envelopes in the tray. I’ve used these same templates, envelopes and printer to print envelopes successfully many times before.

Have I accidently changed a setting somewhere?

Thanks for the help!
